RedWolf is a security threat simulator that tests security system effectiveness. Its threat generation capabilities include email, IM, malware, P2P, social networking, VoIP, DDoS, and many more. The guiding philosophy is that by generating realistic scenarios in a wide variety of categories, an auditor or organization can assess the effectiveness of network defenses. The scenario suite allows one to verify compliance with PCI-DSS, Sarbanes-Oxley, or HIPAA controls. RedWolf helps identify data loss risks and provides expert recommendations concerning risk mitigation. It reports present findings, recommendations, best practices, and blocking guidance in a straightforward, easily readable format. RedWolf also acts as a 'Red Team' agent, running drills to measure the readiness of your operations staff.
